In the production of cement, to increase the cement/clinker ratio and decrease CO2 emission, the most important alternative is to produce mineral admixture incorporated cements (CEM II-III-IV-V) instead of portland cement (CEM I). These cements are usually produced by intergrinding the portland cement clinker and the mineral admixtures. However, the difference between grindabilities of the different components of such cements may cause significant effects on the particle size distribution and many other pro...
Effect of combining different cement clinkers and slag with controlled finenesses on mortar strength and heat of hydration
Çelikkol Koçak, Tümay; Erdoğan, Sinan Turhan; Department of Civil Engineering (2013)
Portland cement production is an energy consuming activity. Increasing efficiency in concrete production is one of the ways of reducing energy consumption. To improve the efficiency of the properties of both materials and concrete system, reduction of undesired effects (loss of strength, decrease in lifetime, etc.) is important. The main purpose of this study is to combine different Portland cement clinkers and blast furnace slag with different fineness to obtain a cement with a controlled grading, in order...
Effect of trass, granulated blast furnace slag and fly ash on delayed ettringite formation
Topbaş, Selim; Tokyay, Mustafa; Hoşten, Çetin; Department of Cement Engineering (2010)
Properly proportioned, placed and cured concrete can be durable under most conditions. However, deterioration of concrete does occur under certain environments. One of the problems that affect the durability of hardened concrete is delayed ettringite formation (DEF) which is an important problem encountered in precast concrete industry where high temperature curing is applied. Although there had been many researches on DEF, there are still many uncertainties about its chemistry and mechanism. In this study,...
